摘要： A method for controlling the motion of a mobile warning triangle for suitable placement on a roadway acquires information as to color of the lane markings detected by a sensor. When the mobile warning triangle is first placed on the roadway, the sensor is preset in position to detect the lane marking. White or yellow color information of the lane marking or of the black-colored roadway are detected or are not detected by the sensor, and deviations from a required path are recognized when different colors are received in certain combinations by the sensor. If no deviation is recognized in the colors, the mobile warning triangle continues moving forward. If a deviation in colors is recognized, the mobile warning triangle is controlled to hunt to the left and right through one or more predetermined angles to try to detect or redetect the lane marking.

摘要： A method for controlling a mobile warning triangle to move along a lane marking controls the mobile warning triangle to move forward and acquire color information of the lane marking detected by a first sensor and a second sensor of the mobile warning triangle when the mobile warning triangle is placed to allow the first sensor to detect the lane marking of the lane. The color information detected by the first sensor is recognized or not recognized as a color of the lane marking, if yes, controlling the mobile warning triangle to continue moving forward. If not recognized, determining whether the color information detected by the second sensor is the color of the lane marking and if yes, correcting a moving direction of the mobile warning triangle to a first direction by a first predetermined angle or repetitions of the predetermined angle to continue moving forward.

摘要： A method for controlling the motion of a mobile warning triangle for placement behind a stationary vehicle on a roadway acquires color information of the lane markings detected by a first sensor, a second sensor, and a third sensor of the mobile warning triangle. When the mobile warning triangle is placed on the roadway, the first to third sensors are preset in position to detect the lane markings and their colors. The white or yellow color information of the lane markings or of the black-colored roadway are detected or not detected on an individual basis by the sensors and deviations from a required path are recognized when different colors are received in certain combinations by the sensors. If no deviation is recognized in the colors, the mobile warning triangle is controlled to continue moving forward.
